inlineexplicit

Explicit conversion between forward/reverse iterators.

Translate between forward and reverse iterators without changing range boundaries. The resulting iterator will dereference (and have a handle) to the previous node, which is somewhat unexpected; but converting the two endpoints in a range will give the same range in reverse.

This matches std::reverse_iterator conversions.

◆ getReverse()

inline

Get a reverse iterator to the same node.

Gives a reverse iterator that will dereference (and have a handle) to the same node. Converting the endpoint iterators in a range will give a different range; for range operations, use the explicit conversions.
